Updated with trailer (below): Marvel's Avengers lineup continues to expand, but this time in animation. With the new film, created with their anime partners Madhouse, Marvel is shining the spotlight on two of their street level heroes with a dirty way of handling their business.

Marvel's Avengers Confidential: Black Widow and Punisher focuses on the two characters teaming up after Punisher is taken into custody by S.H.I.E.L.D. They're up against a new terrorist organization called "Leviathan" that has been stealing S.H.I.E.L.D. tech.

Interesting to note is the rest of the Avengers shown in the initial trailer. It's very familiar looking to film fans, with Iron Man, Thor, War Machine, Hulk, and Hawkeye all featured alongside Black Widow (not to mention Nick Fury and Maria Hill). Then there's Carol Danvers, Captain Marvel, in her fully updated look. Could it be a hint to Carol making her big-screen live-action debut sooner rather than later, as has been wildly speculated?
